After TSM upgraded, LiteSpeed Console Backups are failing with this error: TSM Client not installed (could not load tsmapi64.dll). command line backups do not get that error, however.
We upgraded LiteSpeed in an attempt to fix this problem and then the error is:
Msg 60300 Level 16, State 1, Line 1
Backup of Database "master" failed.
Unable to setup the TSM Environment with 'D:\tsm_MLICLDC.OPT'
Backups from the command line do not get the error and complete successfully. Just the backups run from the LiteSpeed console get that error of the TSM client not installed.
TSM client is 64-bit; the problem is not what is discussed in the knowledge articles below.
